Think you've got what it takes to detox for 21 days? Here's how one woman did it, why (perfect skin, anyone?), and the info you need to decide if this plan is for you

Last day! I'm so excited this little detox experiment is almost over. I keep daydreaming about what "normal" food I'm going to eat first tomorrow. I cheated a bit last night with a glass of wine (my first in three weeks), but it was my high school reunion -- you didn't expect me to stay totally sober, did you? I do have to admit it was nice to go to my reunion basically weighing what I did in high school; I don't think I've been this light (91.8 pounds) since then.

Since it's my last day (and to make up for last night's wine), I tried not to cheat at all. And I've got more energy than I've had in weeks. Tomorrow morning I get the results of my follow-up skin analysis. I can't wait to see if I improved.
